Creative process discussion

I'd love to hear about how you create your favorite works. Of anything. How did you write your best music? How did you create your favorite character in a story you wrote? Anything of the sort.

I'd love to hear all the different processes people have. It's really quite an interesting topic of discussion, for me.

Personally, I grab a cup of coffee and listen to instrumental music (mostly avant-garde jazz [Coltrane, Washington, etc]) while creating the world of the story I'm writing. There's something very productive-feeling about being wired on caffeine while also having a constant noise in your ears. It's how I compose some of my better characters and settings.

Due to my constant writer's block phenomenon, sometimes I'll smoke some pot to get past it. It's almost like phasing through a wall you can't jump over. There's something lifting about it.
